ATT'Y WILLIAM GOULD AND HERBERT WILLIAM GOULD, OF WILLESDEN, LONDONyENGLAND.,

HOT-WATER HEATING APPARATUS.

Application filed October 17, 1913.

T0 all lwhom t may concern.'

Be it known that we, WILLIAM GOULD and HERBERT WILLIAM GoULD, subjectsof the King of Great Britain, residing at 1 All -Souls avenue,Willesden, London, N. W.,

England, have invented new and useful Improvements in 'Hot-WaterHeatingApparatus, of which the following is a specification.

This invention relates to automatic systems of heating and circulatinghot water, the ob]- ect being to permit a heating system to bc installedwithout regard to the position of the boiler or heating means and tosiniplify and reduce the cost of installation and accelerate andmaintain an automatic and continuous circulation.

In carrying this invention into practice, instead of conveying the pipefrom the boiler or heating means up through atank to a point above thelevel of the water in the system, we subdivide the tank into two or morecompartments by partitions or walls. These partitions are arranged orconstructed so that the compartments communicate, the one with the otheralternately, at` a point above the level of the water 1n the' system andbelow the level of the water.

In order that the invention may be clearly understood and easily carriedinto practice we have appended the accompanying draw- In s.

Figure lis a view showing in elevation one form of hot waterdistributing tank embodying our invention having applied thereto a coldwater supply tank.

Fig. 2 shows the tank as it may be incorporated in a heating system.

Fig. 3 is a top plan view of the distributing tank.

Fig. 4 is a sectional view taken on the line 4-4 of Fig. l.

Fig. 5 is a view similar to Fig. 4, showing a modified partition coverstructure.

Fig. 6 is an elevation of the distributing tank showing a slightmodification.

Fig. 7 is an elevation of the distributing tank and supply tank showinga further modification.

Referring to Figs. 1 to 4 inclusive, A rep* resents the hot waterdistributing tank and B the cold water feed tank which may be separate(as shown) or suitably combined with tank A. The tank A is provided withoutlet or distributing pipe or pipes D through which the water passes tocirculate Specification of Letters Patent.

through the radiators. The tank B may be fitted with the usual supplypipe Z), the supply of water from the tank B to tank A passing through apipe 1), preferably connected to the underside ofthe tanks.

The tank A is subdivided into two or more compartments of the requisitesize by dividing walls or partitions. The pipe al, through which the hotwater passes from the boiler L to the tank A, communicates, as shownbest in Fig. l, with the compartment in the said tank A formed by thewall or partition a2, which wall or partition either extends a certaindistance above thc level of the water in the System. Or the partitionmay extend to the full height of the interior of said tank A, and in thelatter case a perforation or perforations P2 is or are made in the saidwall or partition a2 at a point above the level of the water in thesystem, as shown in Fig. 5. The partition or wall a3 in said tank Aextends from the upperinner wall to within a short distance of thebottom or lower wall. Or this partition or wall 0&3 may extend the fulldepth of the tank A, in which case a perforation or perforations p3 isor are formed in said wall or partition a3 near the ylower part, aslikewise shown in Fig. 5.

There may be a number of these walls or partitions, each alternate onecommunicating with the succeeding compartment near the upper part andthe intermediate ones communicating with the succeeding compartment nearthe lower part.

The operation of the system is as follows When the system is iilled withcold water, the level in all compartments of the tank A is at the pointindicated by the dot and dash line W L in Fig. 1. The boiler L is thenstarted up, and the water heated thereby rises in the pipe al due to itslower density. When the water reaches the top of the partition a2 itflows over into the space between the partitions a2 and a3, and as thispassage is somewhat restricted, when the iiow is sutlicient the entirespace above the original water level in the iirst two compartmentsbecomes lled with water, the air which originally filled this vspacehaving been carried over by the water into the compartments beyond thepartition a3. From these latter compartments the water liows through thedistributing pipes D to the radiators and thence back to the boiler,where either side.

with a media-lly disposed compartment in tank A having adjacentcompartments on In Veach case the dividing walls or partitions of suchcompartment communicate with the adjacent compartments at apointadjacent to the upper end' of the tank, which will be -above the levelof the water in the system. An arrangement of this kind is shown by Fig.6.

It will also be evident that pipe al may communicate with an independenttank E, as shown by Fig. 7, such independent tank communicating, at apoint above the level of thev water in the system, with a distributingtank either with or without a dividing wall or partition or partitions.Or the independent tank may communicate with the pipes circulating thewater throughout the system, at a point above the level of the water inthe system. We are aware vthe use of the upper portion of the pipeleading from the boiler has been suggestedfor this purpose.

Having thu's fully described our invention, what we claim as new anddesire to secure by Letters Patent is:-

1. In a hot water circulating system, the combination of a distributingtank formed with a plurality of vertical partitions dividing said'tankinto a plurality of compart- In this way ments, said partitions havingopenings providing communication between said compartments alternatelyatthe top and'bot- Y tom of the tank, a supply pipe communicating with'one of said compartments, and a plurality of distributing pipesleading. from the bottoms of other of said compartments, there beingonly. one. distributing pipe leading from any one compartment. Y

2. In a hot water circulating system, the combination of a distributingtank formed with a plurality of: v'erticalLpartitions dividing said tankYinto a Yplurality of compartments, .certain-of saidpartitions beingsecured *tol the upper wallv of said tank and terminating labovel theVlower wallV thereof, and the remaining. partitions being secured to thelower wall of said'tank and terminating below the upperv wallvthereof,and arranged in alternaterelation to the partitions secured'to theupperl wall, a-'supply pipe communicating lwith Vone outermostycompartment, and a* plurality of distributing pipes leading from thebottoms of all of the other compartments, except that compartmentadjacent to the lcompartment with which the. supply` pipe communicates.
